JUAN MEDINA/REUTERSCatalan politician Josep Rull arrives to the Supreme Court after being summoned and facing investigation for his part in Catalonia's bid for independence in Madrid, Spain, on March 23, 2018.

Two more jailed Catalan separatist leaders awaiting trial for their role in the region’s failed bid to secede from Spain joined a hunger strike started two days ago by two of their companions to protest against their treatment by Spanish courts.

After Catalonia declared independence last year, Madrid took direct control of the region and brought charges including misuse of public funds and rebellion against Catalan leaders, nine of whom are in jail awaiting trial, Reuters reported.

Two of the leaders in custody, Josep Rull and Joaquim Forn, released a statement saying they would join the hunger strike started on Saturday by Jordi Sanchez and Jordi Turull.

“We also voluntarily renounce food intake as of 8:00 p.m. on Monday,” the men said in a statement.

The men said they were fasting to support Sanchez and Turull’s protest against the failure of Spanish courts to process numerous appeals in relation to their cases.
